OIL-BAFFLING DEVICE.

Application filed May 21, 1923. Serial No. 640,616.

I specification.

This invention relates to improvements in oil baffling devicesarticularly adapted for use on internal combustionengines, and designedto be located between the cylinder of the engine and the spark plug.

In internal combustion engines oil is frequently drawn into the cylinderduring the reciprocation ofthe piston and such oil is frequentlydeposited on the spark plug and interferes with the proper functioningand well working thereof. 4

Among the objects of the present invention one of the principles is toprovide an adapter for use with the spark-plug so that any oil in thecylinder will be arrested before reaching the spark plug and will beburned off in the cylinder thereby insuring the spark plug being keptclean and thus able to perform its functions at all times.

Other objects are to rendermy oil bafliing device or adapter simple inconstruction with the several parts easily accessible for inspection,and capable of being used on all types of internal combustion engines atpresent in use, to so construct the adapter that it is strong anddurable and not liable to go out of repair, and topermit of its beingassembled on an internal combusti0n engine with a minimum of timeandlabour.

With the above and other objects in view which will be made clear as thespecification proceeds my invention resides in the improved constructionand arrangement of parts particularly described in the followingspecification, illustrated in the accompan ing drawings and set forth inthe appen ed claim.

While I have illustrated a preferred embodiment of my invention I do notwish to limit myself to the particular construction disclosed butreserve the. right to modify such construction within the scope of myappended claim.

Fig. 2 isa vertical section of the same. Q

Fig. 3 is a plan view of the lower end of my oil baffling device oradapter.

Fig. 4 is a side elevation of an alternative form of my invention.

Fig. 5 is a vertical section of the same but ilzaken at a differentplane to that shown in Fig. 6 is a plan view of the lower end of thisalternative form of my invention.

Fig. 7 is a front elevation of the Archimedes screw utilized in my oilbaflling device or adapter.

Like characters of reference refer to like parts in the several figures.1 Referring to the drawings and particularly to Figures 1 to 3 and myinvention consists of the adapter 1 which is formed of metal andprovided intermediate of its length with a suitable shoulder below whichthe exterior of the adapter is threaded as shown at 2, while the extremelower end is reduced and provided with a plurality of orifices 4, theobject of which will be made clear hereafter.

The upper portion of my adapter is formed like a nut as illustrated at 1to permit of the adapter being engagedby a spanner and so tightened intoposition on an engine cylinder.

The upper end of thb adapter is internally threaded as shown at 5 toengage the lower threaded end of a spark plug.

The bore is reduced towards and provided with a shoulder adjacent to theorifices 4: and an Archimedes screw 10 is housed within this board andformed with an extension or lug which is provided with an orifice 10designed to be engaged by a cotter pin 3 which passes through the lowerend of my adapter and so secures the said screw in position.

By reducing the lower end of my adapter ample clearance is provided forthe cotter pin 3.

Referring now to that form of the invention illustrated in Figs. 4 to 6the only difference existing with the above "described figures is thatthe lower screw threaded portion 8 is tapered and the upper internallyscrew threaded portion 9 is also tapered.

The exterior of the adapter is otherwise the same having a nut likeportion 7 adapted to be engaged by a spanner.

the lower end When my adapter is in use the spark plug is threaded intothe upper end of the e adapter at 5 or 9 while the lower end of theadapter makes threaded engagement at 2 or 8 with the internal combustionengine.

The oil in the cylinder of the engine tending to enter the bore of theadapter impinges'on the screw 10 and flows down the same and passesthrough the orifices 4 into the cylinder where it is burned so that thespark plug at all times is kept in a clean condition and is able toperform its required functions. v From" the above description it will beseen that I have invented an oil bafiiing device for i use in internalcombustion engines which device is simple in construction and reliable 1its operations.

- I claim- An oil bafliing device for spark plugs com- 20.

of the shell below the internal threads being 25 smoothly bored tonearly the end of the shell and counter bored of a smaller diameter tothe end forming an internal shoulder, said shoulder adapted to supportan oil baflie element in the form of an Archimedes screw, said screwhaving a depending tongue and locking means cooperating with said tongueand the lower end of said shell to secure said screw in position.
